<!--
    Sections auto-number themselves and their paragraphs. The chosen number can
    be overridden by setting the 'number' attribute. A paragraph can also be
    marked as a continuation of the previous paragraph (without its own number)
    by giving it a 'cont' class.

    Also recognizes attributes 'id' and 'title', but marking these as attributes
    cause problems for the ShadowDOM polyfill.
